It may sound old-fashioned, but letters and phone calls to

“When I was sixteen, I had just two things on my mind - girls and cars. I wasn't very good with girls. So I thought about cars. I thought about girls, too, but I had more luck with cars. Let's say that when I turned sixteen, a genie had appeared to me. And that genie said, 'Warren, I'm going to give you the car of your choice. It'll be here tomorrow morning with a big bow tied on it. Brand-new. And it's all yours.' Having heard all the genie stories, I would say, 'What's the catch?' And the genie would answer, 'There's only one catch. This is the last car you're ever going to ge tin your life. So it's got to last a lifetime.' If that had happened, I would have picked out that car. But, can you imagine, knowing it had to last a lifetime, what I would do with it? I would read the manual about five times. I would always keep it garaged. If there was the least little dent or scratch, I'd have it fixed right away because I wouldn't want it rusting. I would baby that car, because it would have to last a lifetime. That's exactly the position you are in concerning your mind and body. You only get one mind and one body. And it's got to last a lifetime. Now, it's very easy to let them ride for many years. But if you don't take care of that mind and that body, they'll be a wreck forty years later, just life the car would be. It's what you do right now, today, that determines how your mind and body will operate ten, twenty, and thirty years from now.” ― Warren Buffett

“Whatever other resources you may have, you can always use your voice and your vote to effect change.” ― Bill Gates

“[Bill] Gates said he connected with [Eddy] Izzard even though it would appear they have nothing in common — but that might be the point the author is trying to communicate. "I've recently discovered that I have a lot in common with a funny, dyslexic, transgender actor, comedian, escape artist, unicyclist, ultra-marathoner, and pilot from Great Britain. Except all of the above," Gates wrote. "We're all cut from the same cloth. In his words, 'We are all totally different, but we are all exactly the same” ― Bill Gates

“It's nice to have a lot of money, but you know, you don't want to keep it around forever. I prefer buying things. Otherwise, it's a little like saving sex for your old age.” ― Warren Buffett

“Gold is a way of going long on fear, and it has been a pretty good way of going long on fear from time to time. But you really have to hope people become more afraid in a year or two years than they are now. And if they become more afraid you make money, if they become less afraid you lose money, but the gold itself doesn’t produce anything.” ― Warren Buffett

“In fact, when Warren Buffett was once asked about the key to success, he pointed to a stack of nearby books and said, “Read 500 pages like this every day. That’s how knowledge works. It builds up, like compound interest. All of you can do it, but I guarantee not many of you will do it.” ― Warren Buffett

Founding a company is hard. Most of it isn't smooth. You'll have to make very hard decisions. You have to fire a few people. Therefore, if you don't believe in your mission, giving up is easy. The majority of founders give up. But the best founders don't give up. ― Mark Zuckerberg

You can use your real identity, or you can use phone numbers for something like WhatsApp, and pseudonyms for something like Instagram. But in any of those you're not just sharing and consuming content, you are also building relationships with people and building an understanding of people. ― Mark Zuckerberg

It's not that every single thing that happens on Facebook is gonna be good. This is humanity. People use tools for good and bad, but I think that we have a clear responsibility to make sure that the good is amplified and to do everything we can to mitigate the bad. ― Mark Zuckerberg

It's really easy to have a nice philosophy about openness, but moving the world in that direction is a different thing. It requires both understanding where you want to go and being pragmatic about getting there. ― Mark Zuckerberg

“The climate is like a bathtub that’s slowly filling up with water. Even if we slow the flow of water to a trickle, the tub will eventually fill up and water will come spilling out onto the floor. That’s the disaster we have to prevent. Setting a goal to only reduce our emissions—but not eliminate them—won’t do it.” ― Bill Gates

“There’s one last way we can cut down on emissions from the food we eat: by wasting less of it. In Europe, industrialized parts of Asia, and sub-Saharan Africa, more than 20 percent of food is simply thrown away, allowed to rot, or otherwise wasted. In the United States, it’s 40 percent. That’s bad for people who don’t have enough to eat, bad for the economy, and bad for the climate. When wasted food rots, it produces enough methane to cause as much warming as 3.3 billion tons of carbon dioxide each year.” ― Bill Gates

“Earlier, I mentioned a related technology called direct air capture. It involves exactly what the name implies: capturing carbon directly from the air. DAC is more flexible than point capture, because you can do it anywhere. And in all likelihood, it’ll be a crucial part of getting to zero; one study by the National Academy of Sciences found that we’ll need to be removing about 10 billion tons of carbon dioxide a year by mid-century and about 20 billion by the end of the century.” ― Bill Gates

“In the old world, you devoted 30% of your time to building a great service and 70% of your time to shouting about it. In the new world, that inverts.” ― Jeff Bezos

“I wanted to project myself forward to age 80 and say, ‘OK, I’m looking back on my life. I want to minimise the number of regrets I have.’ And I knew that when I was 80, I was not going to regret having tried this. I was not going to regret trying to participate in this thing called the Internet that I thought was going to be a really big deal. I knew that if I failed, I wouldn’t regret that. But I knew the one thing I might regret is not ever having tried. I knew that that would haunt me every day.” ― Jeff Bezos

“When you receive criticism from well-meaning people, it pays to ask, ‘Are they right?’ And if they are, you need to adapt what they’re doing. If they’re not right, if you really have conviction that they’re not right, you need to have that long-term willingness to be misunderstood. It’s a key part of invention.” ― Jeff Bezos

“But Bezos had a rule, which was to use his heart and his intuition as well as empirical data in making a big decision. “There has to be risk taking. You have to have instinct. All the good decisions have to be made that way,” ― Jeff Bezos

“I think it's very important to have a feedback loop, where you're constantly thinking about what you've done and how you could be doing it better.” ― Elon Musk

“Stop being patient and start asking yourself, how do I accomplish my 10-year plan in 6 months? You will probably fail but you will be a lot further ahead of the person who simply accepted it was going to take 10 years.” ― Elon Musk

“I could go and buy one of the islands in the Bahamas and turn it into my personal fiefdom, but I am much more interested in trying to build and create a new company.” ― Elon Musk
